Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583598, here are decompositions:

37 + 31583561 = 31583598
71 + 31583527 = 31583598
89 + 31583509 = 31583598
149 + 31583449 = 31583598
317 + 31583281 = 31583598
439 + 31583159 = 31583598
461 + 31583137 = 31583598
467 + 31583131 = 31583598

Showing the first eight; more decompositions exist.
